Catch ActivityNotFoundException when launching GlobalSearchActivity.

When the left panel is set to launch the Global Search Activity, this
can throw an ActivityNotFoundException if the application is updating
while the user swipes to the left. Catch this exception and log it in
the occurance of this unlikely timing.
